Review on 'Avatar'

I just saw the movie 'Avatar' online. It was a 2009 science fiction movie but I just saw it today as I heard that the film is interesting. At first, I don't really understand what it is talking about and I found it quite boring. However, after the film is halfway through, the story is getting interesting a little and I think I have roughly got an idea what is it all about.

My thoughts for the movie? It also involves love relationship besides scientific materials in the movie. The ending part looks familiar as the movie in 'Brother Bear'. In 'Avatar', Jake Sully is willing to transform himself into a Na'vi avatar all because of his love for Neytiri (I guess). The effects and graphics in the movie are great, but I prefer the graphics like in 'Brother Bear'. For those who likes science fiction plot would like 'Avatar'. Okay, some graphics from 'Avatar' which I think it's nice.
